Patent DE-19909109-A1 (DE)
Inventor: SCHMITZ GUENTER
IPC: F01L9/20
Filed: 1999-03-03
Abstract: The invention relates to a method for detecting a movement, notably for controlling the speed at which an armature arrives at an electromagnetic actuator. Said actuator  comprises at least one electromagnet which has at least one pole face and is connected to a controllable current supply, and an armature which is connected to a control member to be actuated and when the electromagnet is supplied with a current can be moved against the force of a return spring from a first switching position in the direction of the pole face of the electromagnet into a second switching position assigned to said pole face. Via at least one direction sensor assigned to the electromagnet the alignment of a magnetic leakage field, which changes as the armature approaches, is detected and a control signal for the current supply is generated in accordance with the change in alignment.
Patent DE-19913668-A1 (DE)
Inventor: SCHUCKMANN ALFRED VON
IPC: B05B11/00
Filed: 1999-03-25
Abstract: The invention relates to a pump (4) which can be actuated by means of a hand lever. Said pump is used for spraying liquids and can be especially mounted on bottles (1) or the like. The pump comprises a piston (10) that can be displaced in a linear manner (line x-x) in a pump chamber (9) on the side of the housing. The piston (10) serves for jetting the liquid (3) from a mouth piece nozzle (18). The piston (10) is coupled to the hand lever (6) via a connection piece (G) in such a way that the swivelling movement of the hand lever (6) draws the piston in the direction of the liquid that flows towards the mouth piece nozzle (18). The aim of the invention is to produce the inventive pump in a simple manner and so that it can be used reliably. To this end, the connection and tractional member (G) extends from the rear side (34) of the piston (10), parallel to the displacement path of the piston and in the direction of the mouth piece nozzle (18).

Patent DE-19915139-A1 (DE)
Inventor: HEITMANN WALTER
IPC: G02B6/34
Filed: 1999-03-26
Abstract: The invention relates to a cost-effective solution for compensating the dispersion of optical signals with different wavelengths. According to the invention, photonic crystals (K1-Kn) are arranged on a common optical waveguide (2). Each photonic crystal (K1-Kn) is set in such a way that it reflects or deflects the signals of one wavelength and allows the signals of other wavelengths to pass through unattenuated. The actual arrangement of the photonic crystals (K1-Kn) on the optical waveguide (2) and the actual arrangement of the deflective elements in the photonic crystal are determined according to the dispersion which is to be compensated between the individual wavelengths. The inventive solution enables high-quality photonic dispersion compensators which are approximately 1000 times shorter than conventional diffraction gratings to be set or adjusted in a fixed manner.
